How can I use one query/rcon client multiple times?

Sorry for the late response.

In your while loop, you have already closed the client after the first iteration, since you are using it inside a try-witch-resources block. You cannot re-use the same instance after closing it.

The rule of thumb is to only instantiate the client once (as it can be expensive) and close it once you are done using it.

Moving the client reference out of your while loop should fix it.

@Test
public void check() throws InterruptedException {
    int count = 1;
    Server server = new Server();
    server.setAddress("192.168.3.3:27005");

    try (SourceQueryClient sourceQueryClient = getClient()) {
        while (true) {
            int finalCount = count;
            final CountDownLatch latch = new CountDownLatch(1);
            System.out.printf("[%d] Request\n", finalCount);
            sourceQueryClient.getInfo(server.getInetAddress()).whenComplete((info, error) -> {
                latch.countDown();
                if (error != null) {
                    server.SetDownStatus();
                    return;
                }
                System.out.printf("[%d] Player count: %d\n", finalCount, info.getResult().getNumOfPlayers());
            });
            latch.await();
            count++;
            Thread.sleep(500);
        }
    } catch (CompletionException | IOException err) {
        err.printStackTrace();
    }
}

public SourceQueryClient getClient() {
    if (sourceQueryClient == null) sourceQueryClient = new SourceQueryClient();
    return sourceQueryClient;
}
